2010 Nebraska Water Monitoring Programs Report, Marty Link

Nebraska Department of Environmental Quality: Reports

The Nebraska Department of Environmental Quality (NDEQ) is charged with monitoring, assessing, and to the extent possible, managing the state’s water resources. The purpose of this work is to protect and maintain good quality water and encourage or execute activities to improve poor water quality. Monitoring is done on the over 18,000 miles of flowing rivers and streams, our greater than 280,000 acres of surface water in lakes and reservoirs, and the vast storage of groundwater in Nebraska’s aquifers.

Morphological Changes And Immunohistochemical Expression Of Rage And Its Ligands In The Sciatic Nerve Of Hyperglycemic Pig (Sus Scrofa), Judyta K. Juranek, Alexey Aleshin, Eileen M. Rattigan, Lynne Johnson, Wu Qu, Fei Song, Radha Ananthakrishnan, Nosirudeen Quadri, Shi Du Yan, Ravichandran Ramasamy, Ann Marie Schmidt, Matthew S. Geddis

Publications and Research

The aim of our project was to study the effect of streptozotocin (STZ)—induced hyperglycemia on sciatic nerve morphology, blood plasma markers and immunohistochemical expression of RAGE (the Receptor for Advanced Glycation End-products), and its ligands—S100B and Carboxymethyl Lysine (CML)-advanced glycation endproduct (AGE) in the laboratory pig. Six months after STZ—injections, blood plasma measurements, morphometric analysis of sciatic nerve fiber density, immunofluorescent distribution of potential molecular neuropathy contributors, ELISA measurement of plasma AGE level and HPLC analysis of sciatic nerve levels of one of the pre-AGE and the glycolysis intermediate products—methyl-glyoxal (MG) were performed. The results of our study revealed that …

When Are Genetic Methods Useful For Estimating Contemporary Abundance And Detecting Population Trends?, David A. Tallmon, Dave Gregovich, Robin Waples, C. Scott Baker, Jennifer Jackson, Barbara L. Taylor, Eric Archer, Karen K. Martien, Fred W. Allendorf, Michael K. Schwartz

United States Department of Commerce: Staff Publications

The utility of microsatellite markers for inferring population size and trend has not been rigorously examined, even though these markers are commonly used to monitor the demography of natural populations. We assessed the ability of a linkage disequilibrium estimator of effective population size (N_e) and a simple capture-recapture estimator of abundance (N) to quantify the size and trend of stable or declining populations (true N = 100–10,000), using simulated Wright–Fisher populations. Neither method accurately or precisely estimated abundance at sample sizes of S = 30 individuals, regardless of true N. However, if larger samples …

Phenotypic Plasticity And Population Viability: The Importance Of Environmental Predictability, Thomas E. Reed, Robin Waples, Daniel E. Schindler, Jeffrey J. Hard, Michael T. Kinnison

United States Department of Commerce: Staff Publications

Phenotypic plasticity plays a key role in modulating how environmental variation influences population dynamics, but we have only rudimentary understanding of how plasticity interacts with the magnitude and predictability of environmental variation to affect population dynamics and persistence. We developed a stochastic individual-based model, in which phenotypes could respond to a temporally fluctuating environmental cue and fitness depended on the match between the phenotype and a randomly fluctuating trait optimum, to assess the absolute fitness and population dynamic consequences of plasticity under different levels of environmental stochasticity and cue reliability. When cue and optimum were tightly correlated, plasticity buffered absolute …

Compromising Genetic Diversity In The Wild: Unmonitored Large-Scale Release Of Plants And Animals, Linda Laikre, Michael K. Schwartz, Robin Waples, Nils Ryman, Gem Working Group

United States Department of Commerce: Staff Publications

Large-scale exploitation of wild animals and plants through fishing, hunting and logging often depends on augmentation through releases of translocated or captively raised individuals. Such releases are performed worldwide in vast numbers. Augmentation can be demographically and economically beneficial but can also cause four types of adverse genetic change to wild populations: (1) loss of genetic variation, (2) loss of adaptations, (3) change of population composition, and (4) change of population structure. While adverse genetic impacts are recognized and documented in fisheries, little effort is devoted to actually monitoring them. In forestry and wildlife management, genetic risks associated with releases …

Geographic Variation Of Persistent Organic Pollutant Levels In Humpback Whale (Megaptera Novaeangliae) Feeding Areas Of The North Pacific And North Atlantic, Cristiane T. Elfes, Glenn R. Vanblaricom, Daryle Boyd, John Calambokidis, Phillip J. Clapham, Ronald W. Pearce, Jooke Robbins, Juan Carlos Salinas, Janice M. Straley, Paul R. Wade, Margaret M. Krahn

United States Department of Commerce: Staff Publications

Seasonal feeding behavior and high fidelity to feeding areas allow humpback whales (Megaptera novaeangliae) to be used as biological indicators of regional contamination. Biopsy blubber samples from male individuals (n=67) were collected through SPLASH, a multinational research project, in eight North Pacific feeding grounds. Additional male samples (n=20) were collected from one North Atlantic feeding ground. Persistent organic pollutants were measured in the samples and used to assess contaminant distribution in the study areas. North Atlantic (Gulf of Maine) whales were more contaminated than North Pacific whales, showing the highest levels of polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers …

History And Fate Of A Small Isolated Population Of Weddell Seals At White Island, Antarctica, Thomas S. Gelatt, Corey S. Davis, Ian Stirling, Donald B. Siniff, Curtis Strobeck, Isabelle Delisle

United States Department of Commerce: Staff Publications

Weddell seals (Leptonychotes weddellii Lesson) at White Island, Antarctica form a small, completely enclosed, natural population hypothesized to be of recent origin, likely founded by individuals from nearby Erebus Bay. This population constitutes an ideal model to document a founder event and ensuing genetic drift, with implications for conservation. Here we combined historical accounts, census and tagging data since the late 1960s, and genetic data (41 microsatellite loci and mitochondrial DNA sequences) from 84 individuals representing nearly all individuals present between 1990 and 2000 to investigate the history of the founding of the White Island population, document its population …

Adverse Outcome Pathways And Ecological Risk Assessment: Bridging To Population-Level Effects, Vincent J. Kramer, Matthew A. Etterson, Markus Hecker, Cheryl A. Murphy, Guritno Roesijadi, Daniel J. Spade, Julann A. Spromberg, Magnus Wang, Gerald T. Ankley

United States Department of Commerce: Staff Publications

Maintaining the viability of populations of plants and animals is a key focus for environmental regulation. Population-level responses integrate the cumulative effects of chemical stressors on individuals as those individuals interact with and are affected by their conspecifics, competitors, predators, prey, habitat, and other biotic and abiotic factors. Models of population-level effects of contaminants can integrate information from lower levels of biological organization and feed that information into higher-level community and ecosystem models. As individual-level endpoints are used to predict population responses, this requires that biological responses at lower levels of organization be translated into a form that is usable …

Hierarchical Bayesian Spatial Models For Multispecies Conservation Planning And Monitoring, Carlos Carroll, Devin S. Johnson, Jeffrey R. Dunk, William J. Zielinski

United States Department of Commerce: Staff Publications

Biologists who develop and apply habitat models are often familiar with the statistical challenges posed by their data’s spatial structure but are unsure of whether the use of complex spatial models will increase the utility of model results in planning. We compared the relative performance of nonspatial and hierarchical Bayesian spatial models for three vertebrate and invertebrate taxa of conservation concern (Church’s sideband snails [Monadenia churchi], red tree voles [Arborimus longicaudus], and Pacific fishers [Martes pennanti pacifica]) that provide examples of a range of distributional extents and dispersal abilities. We used presence–absence data derived from regional monitoring programs to develop …

Hydrological Connectivity For Riverine Fish: Measurement Challenges And Research Opportunities, A. H. Fullerton, K. M. Burnett, E. A. Steel, R. L. Flitcroft, G. R. Pess, B. E. Feist, C. E. Torgersen, D. J. Miller, B. L. Sanderson

United States Department of Commerce: Staff Publications

1. In this review,we first summarize how hydrologic connectivity has been studied for riverine fish capable of moving long distances, and then identify research opportunities that have clear conservation significance. Migratory species, such as anadromous salmonids, are good model organisms for understanding ecological connectivity in rivers because the spatial scale over which movements occur among freshwater habitats is large enough to be easily observed with available techniques; they are often economically or culturally valuable with habitats that can be easily fragmented by human activities; and they integrate landscape conditions from multiple surrounding catchment(s) with in-river conditions. Studies have focussed on …

Meridional Patterns In The Deep Scattering Layers And Top Predator Distribution In The Central Equatorial Pacific, Elliott L. Hazen, David W. Johnston

United States Department of Commerce: Staff Publications

The deep scattering layers (DSL) in the central equatorial Pacific form an important prey resource in a relatively oligotrophic habitat. In March of 2006, we used a calibrated 38-kHz SIMRAD EK60 scientific sonar to assess the spatial distribution of the deep scattering layer relative to broad-scale oceanographic features and fine-scale physical and biological measurements. We conducted a single continuous transect from approximately 10°S to 20°N at 170°W while measuring acoustic backscatter, current velocity and direction, temperature, salinity, oxygen, and fluorescence with depth, coincident with marine mammal occurrence. These data were combined with remotely sensed sea surface height, chlorophyll, and sea …

Recent Changes In Density, Biomass, Recruitment, Size Structure, And Nutritional State Of Dreissena Populations In Southern Lake Michigan, Thomas F. Nalepa, David L. Fanslow, Steven A. Pothoven

United States Department of Commerce: Staff Publications

Trends in density, biomass, population structure, and nutritional state of Dreissena polymorpha and Dreissena rostriformis bugensis were examined in southern Lake Michigan between the 1990s and 2008. Density and biomass of D. polymorpha increased to a peak in the early 2000s and then declined. In contrast, D. rostriformis bugensis was first found in the southern basin in 2001 and has continued to increase in density or biomass at all depths ever since. In 2008, maximum mean density of D. rostriformis bugensis occurred at 16–30 m (19,000/m²), but maximum biomass (AFDW) occurred at 31–50 m (43.9 g/m²). …

The Malarial Cdk Pfmrk And Its Effector Pfmat1 Phosphorylate Dna Replication Proteins And Co-Localize In The Nucleus, Dayadevi Jirage, Yueqin Chen, Diana Caridha, Michael T. O’Neil, Fredrick Eyase, William H. Witola, Choukri Ben Mamoun, Norman C. Waters

United States Army: Publications

Cyclin-dependent kinases (CDKs) have an established role in metazoans and yeast in DNA replication, transcription and cell cycle regulation. Several CDKs and their effectors have been identified in the malaria parasite Plasmodium falciparum and their biological functions are beginning to be investigated. Here we report results from the functional characterization of Pfmrk and its effector PfMAT1. We validated the interactions between Pfmrk and PfMAT1 and pinpointed their intracellular location. Co-immunoprecipitation studies demonstrated physical interaction between the two proteins and identified the C-terminal domain of PfMAT1 as the Pfmrk activator domain. Immunofluorescence analyses using GFP and RFP-tagged versions of Pfmrk and …

Prolonged Intensive Dominance Behavior Between Gray Wolves, Canis Lupus, L. David Mech, H. Dean Cluff

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Dominance is one of the most pervasive and important behaviors among wolves in a pack, yet its significance in free-ranging packs has been little studied. Insights into a behavior can often be gained by examining unusual examples of it. In the High Arctic near Eureka, Nunavut, Canada, we videotaped and described an unusually prolonged and intensive behavioral bout between an adult male Gray Wolf (Canis lupus) and a male member of his pack, thought to be a maturing son.With tail raised, the adult approached a male pack mate about 50 m from us and pinned and straddled this …

The State Of The Birds 2010 Report On Climate Change: United States Of America, Brad Bortner, Paul Schmidt, Alicia Frances King, Steve Holmer

United States Fish and Wildlife Service: Publications

Foreword- Birds are telling us an important story about climate change

The first State of the Birds report in 2009 revealed troubling declines of bird populations in the United States during the last 40 years—a warning signal of the failing health of our ecosystems. It also highlighted heartening evidence that concerted conservation efforts can make a positive difference in restoring habitats and reversing declines.

In this 2010 State of the Birds report, we consider one of the greatest environmental challenges of our time, climate change. How will climate change affect birds and their habitats? Accelerated by human activities, climate change …

Microbial Treatment Of Swine Fecal Waste To Generate Long-Chain Linear Alkanes After Fast Pyrolysis, Lisa A. Fitzgerald, C. Ziemer, S. E. Lizewski, Bradley R. Ringeisen, K. Henry, Justin C. Biffinger

United States Navy: Publications

Research into the generation of energy from human and animal waste has been primarily focused on gas production (especially methane and hydrogen). While there is some work concentrated on ethanol and biodiesel creation from wastes (fuels used for ground transportation primarily), increasing research interest has been recently directed toward long chain hydrocarbon production for aviation fuels. Kerosene components from swine fecal waste have been generated from four natural sources: undigested dietary lipids, host lipids excreted in feces, bacterial cell walls and products of bacterial fermentation.

Chlorella Viruses Encode Most, If Not All, Of The Machinery To Glycosylate Their Glycoproteins Independent Of The Endoplasmic Reticulum And Golgi, James L. Van Etten, James Gurnon, Giane M. Yanai-Balser, David Dunigan, Michael V. Graves

Nebraska Center for Virology: Faculty Publications

In contrast to all other viruses that use the host machinery located in the endoplasmic reticulum and Golgi to glycosylate their glycoproteins, the large dsDNA-containing chlorella viruses encode most, if not all, of the components to glycosylate their major capsid proteins. Furthermore, all experimental results indicate that glycosylation occurs independent of the endoplasmic reticulum and Golgi. (Review article)

Activity Of Topical Antimicrobial Agents Against Multidrug-Resistant Bacteria Recovered From Burn Patients, Jessie S. Glasser, Charles H. Guymon, Katrin Mende, Steven E. Wolf, Duane R. Hospenthal, Clinton K. Murray

United States Army: Publications

Background:

Topical antimicrobials are employed for prophylaxis and treatment of burn
wound infections despite no established susceptibility breakpoints, which are becoming vital in an era of multidrug-resistant (MDR) bacteria. We compared two methods of determining topical antimicrobial susceptibilities.

Methods:

Isolates of Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus (MRSA), extended spectrum beta-lactamase (ESBL) producing Klebsiella pneumoniae, and Acinetobacter baumanii-calcoaceticus (ABC) from burn patients were tested using broth microdilution and agar well diffusion to determine minimum inhibitory concentrations (MICs) and zones of inhibition (ZI). Isolates had systemic antibiotic resistance and clonality determined. MDR included resistance to antibiotics in three or more …

Toxicity And Bioaccumulation Of Tnt In Marine Fish In Sediment Exposures, Guilherme R. Lotufo, William Blackburn, Sydney J. Marlborough, John W. Fleeger

United States Army: Publications

The bioaccumulation potential and toxicity of 2, 4, 6-trinitrotoluene (TNT) spiked to sediment was evaluated in juvenile sheeps head minnows (JSHM, Cyprinodon variegatus) and adult freckled blennies (FB, Hypsoblennius ionthas). The JSHM were exposed for 4 days in the presence or absence of a mesh separating fish from sediment. FB were exposed to sediment for 7 days. During the 24-day storage period(4 °C), extensive transformation of spiked TNT occurred and concentrations are expressed as the sum of TNT, aminodinitrotoluenes and diaminonitrotoluenes (Sum TNT), on a dry weight basis. Sum TNT in the overlying water, not exchanged during exposure, …

The brainchild of cellist Yo Yo Ma and his Silk Road Project, Silk Road Connect ‘inspires passion-driven learning by empowering students and educators to seek connections across all areas of study and to follow their interests from the familiar to the foreign. In a spirit of playfulness and investigation, collaboration and creativity, this program invites students to experience learning as a continual process …

The Fiber Of Our Lives: A Conceptual Framework For Looking At Textiles’ Meanings, Beverly Gordon

Textile Society of America: Symposium Proceedings

Based on the model explicated in my forthcoming (Thames & Hudson, Fall 2010) book, The Fiber of Our Lives: Why Textiles Matter, I will present a holistic framework that can be used to articulate and compare the meanings of textiles of any given culture or historic period. The framework considers the range of human activities and concerns, including meeting practical survival needs and securing physical, psychological and psychic protection; social interactions; the propensity to seek and wield power; the communication of ideas and aesthetic expression; and activities geared to transcending the limits of human experience—i.e., the spiritual realm. This approach …

Future Reliquaries, Barbara Heller

Textile Society of America: Symposium Proceedings

As a tapestry weaver, spinner, and dyer, I cherish the handmade. But, as a full-fledged member of the electronic age, I realize that the haptic has had a hard time maintaining its status. My Future Reliquary Series is an attempt to reconcile three apparently separate but, in my mind, connected histories: weaving, computing, and religion.

Weaving is a binary system of up/down, just as computing is a binary system of on/off. The first computer was a jacquard loom, complete with punch cards. The process of mechanization removed the human hand from weaving. In an analogous manner, today’s computers have introduced …

The Way Of Sami Duodji: From Nomadic Necessity To Trademarked Lifestyle, Desiree Koslin

Textile Society of America: Symposium Proceedings

The Sami people of Northwestern Eurasia in Norway, Sweden, Finland and Russia share historical vicissitudes brought upon them with most other First Peoples. Their languages were suppressed, their religion and culture obliterated, and their way of life ultimately condemned to marginality. In a painful process that was first given wider attention in texts of the seventeenth century, the Sami were given few options for survival but to acquiesce and adapt to the dictates issued, largely losing their cultural identity in the process.

Today, thanks to extensive advocacy of Sami activists starting in the 1960s, a reawakened Sami identity is fostered …

Tradition Embraces “The New”: Depictions Of Modernity On Japanese Kurume E-Gasuri Futon-Ji, Ann Marie Moeller

Textile Society of America: Symposium Proceedings

Kurume is a city on Kyushu Island in Japan known for producing dramatic hand-woven e-gasuri (picture ikat) futon-ji (bedding covers). The most famous have a single picture which runs across four or five panels. Both the warp and weft threads were resist dyed using indigo before being woven into a single long and narrow length of fabric. This cloth was then cut into the panel sections and sewn together. Extraordinary skill was required to both accurately tie the areas of thread to be resisted and to maintain a consistent tension when weaving the fabric. This precision produced complex designs with …

Tracing Cochineal Through The Collection Of The Metropolitan Museum, Elena Phipps, Nobuko Shibayama

Textile Society of America: Symposium Proceedings

Cochineal, with its origin in the Americas, by the 16th century was exported throughout the world. From the time of the Spanish encounter with the Americas in the late 15th and early 16th century, a dyestuff for a strong, fast, red color was in high demand. While many archival documents and scholarly writing exist on the use and shipment of cochineal throughout the world, and on its impact on the textile industry, this paper traces the pathway of its use through an examination of artworks in the Metropolitan Museum. Scientific analysis aids the study in the identification of cochineal (and …

Urban Textiles: From Yarn Bombing To Crochet Ivy Chains, Ruth Scheuing

Textile Society of America: Symposium Proceedings

Small hand-knitted little cozies appear in my local neighborhood; overgrown weeds in an urban community garden become a source for materials and inspiration.

These new approaches to textiles by emerging artists explore new aesthetics and explode relationships between process and material and ideas about the use for handmade objects. These artists question the use of galleries as exhibition venues, curators, and juries as judges, and commerce/consumerism around finished objects. Instead they use the street as exhibition space and blogs or flickr sites as venues to create local and global communities.
